Senda: AI Habit Tracker

Senda is a habit tracker with an AI coach. It works offline and has no subscription: buy it once or not at all. MARK A HABIT WITH ONE TAP Open the app and see today's list. One tap to mark, another to undo. No menus, no extra steps, and no sign-up required to start. YOUR STREAKS, PROTECTED • Annual heat map: a full year at a glance, habit by habit. • Streak freeze for days you can't make it. An unexpected event shouldn't erase three months of progress. • Streaks that understand travel: crossing time zones won't break your count, and daylight saving time changes won't either. • Daily habits or habits X times per week. • You can mark past days if you forgot to open the app. AN AI COACH THAT HAS SEEN YOUR DATA • Weekly report: which habit is thriving, which is slipping, and which day of the week you struggle most. • Chat with the coach for things that don't fit in a report: how to adjust a habit that doesn't fit, where to restart, or what to cut when you have too many. • Read your real streaks. No generic motivational quotes. TRULY OFFLINE Habits, check-ins, streaks, the heat map, reminders, and the widget live on your phone. The app works just as well on a plane or in a basement. The only thing that needs internet is the coach, since that's the only part calculated externally. YOUR DATA IS YOURS • Export everything to a file anytime and save it wherever you like. • Import it to another phone and pick up right where you left off. • No mandatory account, no profile, and no selling your data to anyone. ALSO • Home screen widget to mark habits without opening the app. • Custom reminders per habit, at the time you choose. • Light points and levels: to encourage you without turning this into a video game. • Top-tier dark mode, not just a dull gray. • Available in Spanish, English, Portuguese, German, French, Italian, Indonesian, and Hindi. NO SUBSCRIPTION, WE MEAN IT Senda is free and supported by ads. If they bother you, a one-time purchase removes them forever. There are also individual packs, and you can earn streak freezes by watching a video if you want. No purchase ever expires, and nothing renews automatically. There's nothing to cancel because there's no subscription.
